Minnesota mall attack likely premeditated

Adan's attack took place at a mall in St. Cloud, Minnesota on September 17.

Authorities say Adan went to the Crossroads Center mall with two knives and stabbed or cut 10 people before he was shot and killed by an off-duty police officer.

Dahir Ahmed Adan was fatally shot by an off-duty police officer after carrying out his attack in St. Cloud, Minnesota, the Minneapolis Star Tribune reported.

Officials have previously said that Adan is not known to have any contact with global terrorist groups such as ISIS, though FBI Special Agent Rick Thornton said Thursday that he had been radicalized by himself or others during the course of a few months.

Stearns County Attorney Janelle Kendall then stepped to the podium, announcing there will be no charges against Avon Police Officer Jason Falconer and saying it is clear that his use of deadly force in firing on Dahir Adan was justified. Falconer told him to put the steak knives down.

In arguing that it appeared the attack was premeditated, Thornton said compelling evidence included Adan not changing out of his security guard uniform between shifts as he usually did, telling his family he had "work to do tonight". Investigators were told Adan previously showed little interest in religion, he said.

Apple Inc, the maker of the iPhone, earlier this year opposed the FBI's efforts to break into an iPhone recovered from a mass shooter in San Bernardino, Cali., sparking a fierce debate over privacy and national security.

Apple did not immediately respond to a request for comment on Thursday.

But using store video, they laid out a stunning and graphic story of the attacks in minute-by-minute fashion and of a suspect who kept attacking even while shot and bleeding.

"The totality of Dahir Adan's behavior and the actions suggest he may have been radicalized either with the influence of others or on his own", Thornton said.

Adan began attacking people before entering the mall.

The mall videos shown at the news conference showed Adan swinging wildly at an electronics store clerk and stabbing him at least once before the man scrambled away, as well as customers running from a candy store and the store's clerk pulling down a barrier just as Adan approached.

On the way to the mall, the Federal Bureau of Investigation official said, Adan was involved in a hit-and-run with a bicyclist.

Adan fell to the ground multiple times after being shot and still had the knife in hand. Thornton said Adan did not stop to see if the bicyclist was injured. Adan referred to Allah and asked one or more of the 10 victims whether they were Muslim, Anderson has said.

The most jarring part of the presentation was the showing and release of surveillance tape capturing Adan attacking and stabbing a store clerk who had walked to the entrance of his establishment after hearing screaming and commotion from the mall's common area.

Hours after the stabbings, a media agency for the Islamic State in Iraq and Levant (ISIL) took to Twitter to claim credit for the attacks. "That is not the son they knew".
